Abstract: This application describes a packet flow out-of-order detection method. After receiving a first packet from a second node, a first node parses the first packet to obtain a flow segment sequence number of the first packet. After receiving the first packet, the first node continues to receive a second packet from the second node, and parses the second packet to obtain a flow segment sequence number of the second packet. The first packet and the second packet belong to a same packet flow. In view of this, the first node may compare the flow segment sequence number of the first packet with the flow segment sequence number of the second packet, to determine whether the packet flow is out of order.

Abstract: The present invention provides a virtual machine migration method, a switch, a virtual machine system. A switch receives a message sent by a server, where the message is used to enable the switch to discover a connected virtual machine interface; obtains, from the message, an identifier for indicating whether a virtual machine is migrating; and determines whether the virtual machine is a virtual machine migrated to the server according to the identifier indicating whether the virtual machine is migrated. According to the embodiments of the present invention, it may be determined whether an added virtual machine on a server is a newly created one or a migrated one.
